HCP5

HCP5 (HLA Complex P5) is a gene that in humans is encoded by the HCP5 gene. It is located on the short (p) arm of chromosome 6 at position 21. This gene is part of the Major Histocompatibility Complex (MHC) class I molecules, which are involved in the presentation of foreign antigens to the immune system.

Function

The HCP5 gene is involved in the immune response. It is thought to play a role in the presentation of viral antigens to the immune system. The protein encoded by this gene is a non-classical MHC class I molecule, which means it does not present antigens in the same way as classical MHC class I molecules. Instead, it is thought to present viral antigens in a way that is recognized by certain immune cells, leading to an immune response.

Clinical significance

Variations in the HCP5 gene have been associated with susceptibility to HIV infection and progression to AIDS. A specific variant of the HCP5 gene, known as rs2395029, is associated with a slower progression to AIDS in individuals infected with HIV. This variant is also associated with a lower viral load in individuals infected with HIV.
